Packet data
The packet data settings affect all access points using a packet data connection.
Packet data connection
— If you select
When available
and you are in a network
that supports packet data, the device registers to the packet data network and
short messages are sent using a packet data connection. If you select
When
needed
, the device uses a packet data connection only if you start an application
or function that needs it. The packet data connection can be closed when it is not
needed by any application.
If there are no packet data services available and you have chosen
When available
,
the device periodically tries to establish a packet data connection.
Access point
— The access point name is needed when you want to use your device
as a modem with your computer.
High speed packet access
— Enable or disable the use of HSDPA (network service)
in UMTS networks.
When HSDPA support is activated, downloading data such as messages, e-mail,
and browser pages through the cellular network may be faster.
